He needs to learn how to grow a pair and stop being so passive. I'd love to actually see him dunk on someone in a half court set, instead of constantly trying to avoid the contact for some puss lay-up with no chance to go in or a bail out pass. He also needs to learn to move and cut to the basket.

Outside of that, which should be obvious, he needs to improve his ballhandling and to be more aggressive in his rebounding.
